OBJECTIVE The authors aimed to design a score for stratifying patients with brain arteriovenous malformation (BAVM) rupture, based on the likelihood of a poor long-term neurological outcome. METHODS The records of consecutive patients with BAVM hemorrhagic events who had been admitted over a period of 11 years were retrospectively reviewed. Independent predictors of a poor long-term outcome (modified Rankin Scale score ≥ 3) beyond 1 year after admission were identified. A risk stratification scale was developed and compared with the intracranial hemorrhage (ICH) score to predict poor outcome and inpatient mortality...

BACKGROUND: Intraventricular hemorrhage is a major risk factor for neurodevelopmental disabilities in preterm infants. However, few studies have investigated how pregnancy complications responsible for preterm delivery are related to intraventricular hemorrhage. OBJECTIVE: To investigate the association between the main causes of preterm delivery and intraventricular hemorrhage in very preterm infants born in France during 2011 between 22 and 31 weeks of gestation...

We previously found that hematoma worsens hydrocephalus after intraventricular hemorrhage (IVH) via increasing iron deposition and aggravating ependymal cilia injury; therefore, promoting hematoma absorption may be a promising strategy for IVH. Recently, some investigations imply that simvastatin has the ability of accelerating hematoma absorption. Thus, this study was designed to examine the efficacy of simvastatin for IVH in rats. Intracerebral hemorrhage with ventricular extension was induced in adult male Sprague-Dawley rats after autologous blood injection...

Gunshot injuries are the most common cause of penetrating brain injury (PBI) and carry a high morbidity and mortality. The incidence of PBI has increased over the last decade with an estimated 35,000 civilian deaths annually. Patients that survive to reach the hospital require rapid triage and imaging evaluation. CT findings in conjunction with the Glasgow Coma Scale are typically used to determine which patients are surgical candidates. Radiologists should be familiar with the various injury patterns and imaging findings which are poor prognostic indicators, notably brainstem, bilateral hemispheric, multilobar, or transventricular injuries...

BACKGROUND: Prior to heart transplantation, static storage of donor hearts is currently limited to 4-5 h, despite profound hypothermia (4-8 °C). Because heart transplantation is an emergency procedure, improved protection to extend safe storage duration would be advantageous. We investigated whether the naturally respiratory pigment HEMO2life(®), which is effective at hypothermia for the passive release of oxygen via oxygen gradient, could improve long-term preservation. METHODS: Isolated Langendorff-perfused rat hearts (n = 12/group) were equilibrated (20 min) and function (left ventricular developed pressure: LVDP) measured by intraventricular balloon before arrest with cold (7...

A characteristic feature of complex healthy biological systems is the ability to react and adapt to minute changes in the environment. This 'complexity' manifests itself in highly irregular patterns of various physiological measurements. Here, we apply Multiscale Entropy (MSE) analysis to assess the complexity of systemic and cerebral near-infrared spectroscopy (NIRS) signals in a cohort of 61 critically ill preterm infants born at median (range) gestational age of 26 (23-31) weeks, before 24 h of life. We further correlate the complexity of these parameters with brain injury and mortality...

INTRODUCTION: Tuberous sclerosis is associated with three central nervous system pathologies: cortical/subcortical tubers, subependymal nodules (SENs), and subependymal giant cell astrocytomas (SEGAs). Tubers are associated with epilepsy, which is often medication-resistant and often leads to resective surgery. Recently, mammalian target of rapamycin inhibitors (mTORi) have been shown to be effective reducing seizure burden in some patients with tuberous sclerosis complex (TSC)-related refractory epilepsy...

Cardiomyopathy caused by lamin A/C gene (LMNA) mutations (hereafter referred as LMNA cardiomyopathy) is characterized by cardiac conduction abnormalities and left ventricular systolic dysfunction predisposing to heart failure. Previous cardiac transcriptional profiling of Lmna(H222P/H222P) mouse, a small animal model of LMNA cardiomyopathy, suggested decreased WNT/β-catenin signalling. We confirmed decreased WNT/β-catenin signalling in the hearts of these mice by demonstrating decreased β-catenin and WNT proteins...

Intraventricular cavernomas (IVCs) are extremely infrequent and only occur in 2.8 to 10% of patients with cerebral cavernomas. We describe three IVC cases and briefly review previously documented IVC cases in PubMed. Among 136 IVC cases, the mean age of the patients was 36.5 years; the male-to-female ratio was 0.8. The most frequent location was the lateral ventricle (52.6%), and most of the clinical symptoms (74%) were related to mass effects on adjacent brain tissues. Intraventricular hemorrhage occurred in 22...

The cerebrospinal fluid (CSF) pH influences brain interstitial pH and, therefore, brain function. We hypothesized that the choroid plexus epithelium (CPE) expresses the vacuolar H(+)-ATPase (V-ATPase) as an acid extrusion mechanism in the luminal membrane to counteract detrimental elevations in CSF pH. The expression of mRNA corresponding to several V-ATPase subunits was demonstrated by RT-PCR analysis of CPE cells (CPECs) isolated by fluorescence-activated cell sorting. Immunofluorescence and electron microscopy localized the V-ATPase primarily in intracellular vesicles with only a minor fraction in the luminal microvillus area...

BACKGROUND: Prognostic assessments, which are crucial for decision-making in critical illnesses, have shown unsatisfactory reliability. We compared the accuracy of a widely used prognostic score against a model derived from clinical data obtained 5 days after admission for patients with intracerebral hemorrhage (ICH), a condition for which prognostication has proven notoriously challenging and prone to bias. METHODS: Patients enrolled in a prospective observational cohort study of spontaneous ICH underwent hourly Glasgow Coma Scale (GCS) assessment...

BACKGROUND AND PURPOSE: Hemispheric location might influence outcome after intracerebral hemorrhage (ICH). INTERACT suggested higher short-term mortality in right hemispheric ICH, yet statistical imbalances were not addressed. This study aimed at determining the differences in long-term functional outcome in patients with right- vs. left-sided ICH with a priori-defined sub-analysis of lobar vs. deep bleedings. METHODS: Data from a prospective hospital registry were analyzed including patients with ICH admitted between January 2006 and August 2014...
